For solving the technical problem, the utility model provides a following technical scheme:

the rail clutch device comprises a mounting seat, a connecting piece, a pulling piece and a spring, wherein two channels are axially arranged on the mounting seat, a first through hole is formed between the two channels of the mounting seat, the connecting seat is mounted on the mounting seat and provided with a second through hole corresponding to the first through hole, a first connecting hole is further formed, the connecting piece is provided with an upper part and a lower part, a lock tongue is arranged at the top end of the upper part, a limit block is radially and outwards arranged on the side wall of the upper part, the outer diameter of the lower part is smaller than the outer diameter of the upper part, the spring is sleeved on the connecting seat, the spring is abutted between the upper part and the connecting seat, one part of the upper part is arranged in the first through hole, the other part of the upper part is arranged in the second through hole, the lower part is arranged in the second through hole, and, the end part of the pulling piece is provided with a second connecting hole.

The first through hole comprises an embedded groove matched with the limiting block.

The second through hole comprises a limiting groove matched with the limiting block.

The limiting block is of a cuboid structure.

The spring bolt is in a chamfered cylinder shape.

Compared with the prior art, the utility model beneficial effect who has is: this kind of track clutch forms through mount pad, connecting seat, connecting piece, pulling piece and spring equipment, and it can design the shape size of one or several kinds of parts among them as required in order to adapt to different application objects, for example increase the length etc. that pulls the piece, and because this kind of change only needs to change partial part, and need not to change whole product, so its use cost is lower and use very nimble, and easy maintenance is swift simultaneously, and cost of maintenance is low.

Detailed Description

As shown in the figure, the rail clutch device comprises a mounting seat 1, a connecting seat 2, a connecting piece 3, a pulling piece 4 and a spring 5, wherein two channels 11 which are axially arranged are arranged on the mounting seat 1, the channels 11 are used for allowing a chain and a belt to pass through, a first through hole 12 is arranged between the two channels 11 of the mounting seat 1, the connecting seat 2 is arranged on the mounting seat 1 and is provided with a second through hole 21 corresponding to the first through hole 12, and a first connecting hole 22 is also arranged, the first connecting hole 22 is used for being connected with a connecting rod, and the connecting rod is connected with a door body; the connecting piece 3 is provided with an upper part 31 and a lower part 32, the top end of the upper part 31 is provided with a lock tongue 311, the side wall is provided with a limit block 312 outwards along the radial direction, the outer diameter of the lower part 32 is smaller than the outer diameter of the upper part, the spring 5 is sleeved on the upper part, the spring 5 is abutted between the upper part 31 and the connecting seat 2, the spring 5 is used for moving the connecting piece 3 by utilizing the restoring force of the spring and enabling the lock tongue 311 on the connecting piece 3 to extend out of the first through hole 12, one part of the upper part 31 is arranged in the first through hole 12, the other part is arranged in the second through hole 12, the lower part 32 is arranged in the second through hole 21, the end part of the lower part extends out of the second through hole 21 and is hinged with the pulling piece 4, the end part of the pulling piece 4 is provided with a second connecting hole 41, the second, the pulling part 4 and the connecting part 3 move, and the connecting part 3 and the mounting seat 1 move.

In the present embodiment, in order to make the section of the connecting member 3 having the stopper 312 embedded in the first through hole 12 without radial movement, the first through hole 12 includes an embedding groove matched with the stopper 312, and the stopper 31 is embedded in the embedding groove.

In this embodiment, in order to prevent the connecting member 3 from being separated from the second through hole 21 of the connecting base 2 when being pulled, the second through hole 21 includes a limiting groove 211 matched with the limiting block 312, so that even if the pulling member 4 drives the connecting member 3 to move axially along the second through hole 21, the limiting groove 211 can always limit the limiting block 312 therein.

In this embodiment, the limiting block 312 is a rectangular parallelepiped structure.

In this embodiment, the latch tongue 311 is in a chamfered cylinder shape, and the chamfered surface of the structure faces the hole end of the track, so as to facilitate the latch tongue 311 to slide into a tighter lock hole for closing the door through the chamfered surface when the door is locked.

The working principle of the utility model is as follows:

before operation, the rail clutch device is assembled and installed on the rail, and the connecting rod is connected through the first connecting hole 22 and the pull rope is connected through the second connecting hole 41. When the clutch and the track need to be separated, the pull rope is pulled, the pull rope drives the pull piece 4 to move, the pull piece 4 pulls the connecting piece 3 to move, the connecting piece 3 is forced downwards to extrude the spring and move downwards, when the pull piece 4 is straightened, the connecting piece 3 drives the lock tongue 311 to move into the first through hole 12, and at the moment, the clutch and the track are in a separated state because the lock tongue 311 is separated from a lock hole on the track; if the clutch and the rail are in the automatic locking state, the pulling element 4 and the connecting element 3 will be reset by releasing the pulling rope and drive the locking tongue 311 to extend out of the first through hole 12, and in the process of opening and closing the door, the locking tongue 311 will automatically slide into the belt or chain connecting element of the rail or the corresponding rail locking hole.
